Avatar. Mrs B took me last night. Her idea. She regretted it. What a load of tosh! Pretty tosh, but tosh none the less.
I can suspend disbelief for pentadactyl mammalian humanoid aliens (though it's not easy), but some of the rest! The feeble excuse for a plot appeared to be mostly a way of linking together the pictures, plus a bit of very clumsy & extraordinarily naive propagandising about noble savages.
There were a lot of people doing things that just didn't make sense, except to provide Cameron with opportunities to reprise images from other films. There's an awful lot of blatantly & rather tiresomely derivative imagery.
BTW, we both noticed that despite 3D being a large part of the point of the film, Cameron doesn't seem to understand how to use it. I think he can't break out of his training & years of practice in 2D & its conventions. A lot of scenes were very obviously shot according to 2D filmic conventions, which didn't really work in 3D. for example, having only the point of focus in focus doesn't work at all in 3D. Out of focus backgrounds look very wrong indeed when ones mind is telling one your eyes are adjusting their focus for the apparent depth. And things flying towards you (grossly overdone, BTW) should not go out of focus!
